[0002] Stir-frying is an important cooking method in Chinese cuisine, requiring the stove to provide instantaneous intense heat. However, existing gas stoves typically have burners that only have an outer and inner flame ring, and a valve body with two gas outlets. Even at maximum power, the flame output is low, failing to meet the required intensity for stir-frying. This has put new demands on gas stoves, leading to the emergence of gas stoves with a stir-fry mode. Existing gas stoves with a stir-fry mode either have a burner that includes an inner flame ring, an outer flame ring, and a stir-fry ring, and a gas pipeline that includes an inner ring gas circuit, an outer ring gas circuit, and a stir-fry gas circuit. The inner ring, outer ring, and stir-fry ring are connected to the inner ring gas circuit, the outer ring gas circuit, and the stir-fry gas circuit, respectively. The stir-fry gas circuit is equipped with an on / off valve that controls the on / off of the stir-fry gas circuit, enabling or extinguishing the stir-fry ring. Alternatively, the gas stove's valve body has three gas outlets, connected to a high-fire pipe, a low-fire pipe, and a specially designed stir-fry pipe. The stir-fry pipe is opened and closed by controlling the valve body, resulting in a complex structure and inconvenient operation. Summary of the Invention

[0028] Example 1

[0029] See also Figures 1 to 5As shown, this embodiment provides a gas stove, including a valve body 101 and a burner, wherein the first gas output end of the valve body 101 can be communicated with the flame hole of the inner ring fire cover 102 of the burner, and the second gas output end of the valve body 101 is communicated with the flame hole of the outer ring fire cover 103 of the burner. The gas stove also includes a stir-fry control valve 104 and a stir-fry start button 105. The stir-fry control valve 104 has a first gas channel 111 and a second gas channel 112, wherein one end of the first gas channel 111 is communicated with the second gas output end of the valve body 101, and the other end of the first gas channel 111 is communicated with the flame hole of the outer ring fire cover 103 of the burner; the stir-fry start button 105 is connected to the stir-fry control valve 104, and the stir-fry start button 105 is used to control the stir-fry control valve 104 to open when the gas stove is in the maximum fire state, so that the second gas channel 112 is communicated with the first gas channel 111.

[0030] Based on this structure, the gas stove provided in this embodiment does not change the structure of the existing burner and valve body 101. Instead, a stir-fry control valve is provided between the second gas output end of the valve body 101 and the outer ring flame cover 103 of the burner, and the stir-fry control valve 104 is activated by the stir-fry start button 105, thereby quickly realizing a one-button stir-fry mode. During use, the burner is ignited, and the gas enters the first gas channel 111 through the first gas output end, igniting the inner ring flame and simultaneously igniting the outer ring flame, realizing the normal flame combustion mode. When the stir-fry mode needs to be activated, the stir-fry start button 105 is triggered at the maximum flame state, so that the second gas channel 112 is connected to the first gas channel 111, increasing the gas flow of the outer ring flame cover 103, thereby increasing the firepower.

[0031] The gas stove provided in this embodiment includes two burners, realizing independent control of a single burner.

[0032] It should be noted that dual burners or multiple burners can also be controlled simultaneously.

[0033] Furthermore, in some optional embodiments, the gas stove further includes a controller 106 , and the valve body 101 , the stir-fry start button 105 and the stir-fry control valve 104 are all connected to the controller 106 .

[0034] When the gas stove is in the maximum fire state, the stir-fry control valve 104 is triggered, and the controller 106 sends an instruction to the stir-fry control valve 104. The stir-fry control valve 104 opens, and the second gas channel 112 is connected to the first gas channel 111, increasing the gas flow of the outer ring fire cover 103, thereby increasing the firepower and realizing the super-high firepower stir-fry mode. At this time, the firepower can reach more than 5.2kW.

[0035] The controller 106 in this embodiment may be an existing MCU controller, for example, or a PLC controller, such as S7-200.

[0036] Furthermore, in some optional embodiments, the gas stove further includes an indicator light 107 , which is connected to the controller 106 .

[0037] When the controller 106 sends a command to the stir-fry control valve 104, it also sends a command to the indicator light 107. The indicator light 107 lights up to remind the user that the stir-fry mode has been started.

[0038] Furthermore, in some optional embodiments, the gas stove further includes an adjustment switch and an igniter 109 , and the adjustment switch is connected to the igniter 109 and the valve body 101 .

[0039] In this embodiment, the regulating switch is the existing knob 108, and the knob 108 is rotated to adjust the fire on, off and the fire power.

[0040] In this embodiment, a potentiometer 110 is integrated on the valve body 101 to detect the rotation angle of the knob 108. For example, when the knob 108 is rotated to the 90° position, the maximum flame state is reached, at which time the stir-fry start button 105 is triggered to start the stir-fry mode. When the user does not need the stir-fry mode, he only needs to turn the knob 108 to reduce the flame. At this time, the potentiometer 110 detects that the knob 108 has been rotated and sends a signal to the controller 106. The controller 106 sends an instruction to the stir-fry control valve 104, which closes the stir-fry control valve 104. The valve stem cuts off the second gas channel 112, disconnecting the second gas channel 112 from the first gas channel 111. Gas only enters the outer ring flame cover 103 through the first gas channel 111, reducing the amount of outer ring flame gas. At the same time, the controller 106 sends an instruction to the indicator light 107, which goes out, indicating that the user has entered the normal flame combustion mode.

[0041] It should be noted that a micro switch or a Hall switch may also be integrated on the valve body 101 .

[0042] It should be noted that the adjustment switch can also be a touch pad.

[0043] Furthermore, in some optional embodiments, the stir-fry start key 105 is a touch key.

[0044] The stir-fry start key 105 is set as a touch key with high sensitivity, which is convenient for users to operate.

[0045] Furthermore, in some optional embodiments, an outer ring nozzle 113 is provided at the other end of the first gas channel 111 , and the outer ring nozzle 113 is communicated with the flame injection hole of the outer ring fire cover 103 of the burner.

[0046] By providing the outer ring nozzle 113 , the fuel gas can enter the flame injection holes of the outer ring fire cover 103 of the burner through the outer ring nozzle 113 .

[0047] Furthermore, in certain optional embodiments, the gas stove also includes an inner ring nozzle 114, the first gas output end of the valve body 101 is connected to one end of the inner ring nozzle 114 through the pipeline, and the other end of the inner ring nozzle 114 is connected to the flame hole of the inner ring fire cover 102 of the burner.

[0048] By providing the inner ring nozzle 114 , the fuel gas can enter the flame injection holes of the inner ring fire cover 102 of the burner through the inner ring nozzle 114 .

[0049] Furthermore, in some optional embodiments, the stir-fry control valve 104 is a solenoid valve.

[0050] Furthermore, in some optional embodiments, the stir-fry control valve 104 and the valve body 101 are integrally formed.

[0051] Integrating the stir-fry control valve 104 and the valve body 101 into one body can reduce the number of parts and further simplify the structure and cost of the gas stove.

[0052] Example 2

[0053] This embodiment provides a method for controlling a gas stove, which includes the following steps:

[0054] S1. The burner ignites and enters the normal flame combustion mode;

[0055] S2. Under the maximum fire state, trigger the stir-fry start button to open the stir-fry control valve to connect the second gas channel with the first gas channel and enter the stir-fry mode.

[0056] The control method of the gas stove provided in this embodiment is applied to the gas stove. When in use, the burner is ignited, and the gas enters the first gas channel through the first gas output end, ignites the inner ring flame, and simultaneously ignites the outer ring flame, realizing the ordinary flame combustion mode; in the maximum fire state, the stir-fry start button is triggered, and the stir-fry control valve is opened, so that the second gas channel is connected to the first gas channel, increasing the gas flow of the outer ring fire cover, thereby increasing the firepower, and realizing the one-button stir-fry mode.

[0057] Optionally, in the normal flame combustion mode, the size of the fire can be adjusted in a manner substantially the same as that of the prior art. In this embodiment, the knob 108 is rotated to adjust the fire on, off, and the size of the fire.

[0058] As mentioned before, when the user does not need the stir-fry mode, he only needs to turn the knob 108 to reduce the fire, the stir-fry control valve 104 can be closed, the valve stem cuts off the second gas channel 112, the second gas channel 112 is disconnected from the first gas channel 111, and the gas enters the outer ring fire cover 103 only through the first gas channel 111. The amount of outer ring flame gas is reduced. At the same time, the controller 106 sends a command to the indicator light 107, and the indicator light 107 goes out, prompting the user that the normal flame combustion mode has been entered.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
